MACHINE FOR MAKING yFRICTION-VVIIRES.

Specification of Letters Patent No. 29,259, dated July 24, 1860.

foaZZ whom/t may concern:

Be it known that I, DANIEL J. FERRY, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Machinery for one operation, Athe friction wires for frictional Vpriming; in the `manner of guiding the wires in "their manipulation; and in the means by which they are cut ott' a uniform length.

.In order to enable others to make and use my invention, I will now proceed to describe its-construction and operation.

Figures l, 2, and 3 are .longitudinal sections through IJthe `center of my improved machine, with the movingparts in different.

positions. Fig. t is a transverse ysection through the line, 1 2. Fig. 5 through the` line, 3 4, Fig. 6, through the line, 5 6, and Fig. 7, through the line 7 8, ofthe Fig. .1,

looking in the direction of the arrow; the

moving parts in Figs. 6 and 7 being in a diferent position from those in Figs. -L and 5. Fig. S is a plan of the machine, partly in section, with the cross head removed. Fig. 9 is an inverted plan of the cross head of the machine. Fig. 10 is a detached view ot the tool, D. Fig. 11 is a view of the wire in its untouched state. Fig. 12 is a view of the wire after being pressed out. Fig. 13 a view of the wire after being punched and cut oli.

A is the cast iron base of the machine. b B, B are guide rods firmly secured in the ase.

C is a cross head secured to and receiving a reciprocating motion from the ram of an ordinary drop press, and guided by the rods, B B.

7D and E are tools secured to the cross head, C, the distance between which is regulated by the length that the wires are required. The bottom of the tool, D, is made at to within a short distance of its inner edge, where it meets a projection, a which drops down solid for about two diameters of the wire and then has an angular opening cut from edge to edge, as shown in Figs. 1

and l0; th-e breadth of the fiat portion of the tool is made `to correspond to the length andthe thickness to the breadth of the {iattened portion ofthe wire; the breadth of the projection, a is made about'one third of the breadth of the fiat of the tool. The tool, E is made the same breadth and thickness as the tool, D; lits bottom is made flat, equal in. extent to the same part of the tool, D, and extending from the outer edge of the tool toA the projection, y; from thev projection, y, the sides of the tool, from the bottom up a short distance, are indented to within an eighth of `an inch of the outer-edge, where they, contract to about the diameter of the wire and so continue outward, as shown in fFig. 9; the projection, g/ has angular opening starting from the flatof the tool and cut from edge to edge, as shown in Figs. l and 6.

G is a guide secured to the base, A and having an opening through .it in line with the center of the tools, D and E, through which the wire passes to be operated upon. F 1S a die dovetailed mto the base, A; 79 is a continua-tion of the guide, G; 1s an .indentation formed immediately under the flat of the tool, -D and makmgthe rib upon vthe wire when flattened.; j 1s an opening m which the projection, L of the tool, D works, its unbroken edge acting with the above mentioned projection to cut oi' the wire; g is an opening in whichtheprojection, y of the tool, rE works; 7c is an opening extending from the opening, f to the opening, g and slightly Vgreater than the diameter of the wire; g is an opening the sides of which are indented so as to Acorrespond with the indented Yportion of the tool E; 1' is an opening corresponding with the contracted portion of the tool E.

' Z is a rectangular opening through the base, A, of a width equal to that of the openings, f and g, and of a length slightly greater than that of the continuous opening in the die, F.

H is a guide, bolted to the base, A between the tools, D and E, having an opening, c of a width and height sutlicient to allow the wire after being pressed out to pass freely through, and arranged in line with the tools, D and E; the mouth of this opening is made flaring, as shown in the section Fig. 8, so as to meet the wire if inclined a .little to one side or the other and direct it 111 'I is a stop for arresting the further progress of the wire and having a recess, t for centering it.

The operation of the machine is as follows: the attendant first brings the cross head, C down to the position shown in Fig. l, so that the projection, a on the tool, D closes the passage to the opening, c of the guide, H; he then passes the wire through the opening of the guide, G until it is stopped by the projection; the machine is now set in motion, and the flat portion of the tool, D descends upon the wire, pressing it into the indentation, b, and flattening it out; the cross head then ascending carries the projection out of the way and opens the passage to the opening, c, as shown in Fig. 2, when the attendant pushes the wire forward, through the opening, and under the tool, E, until it is arrested by the stop, I. The cross head next descending, the projection, 'y of the tool, E first comes in contact with the wire and directs it, if out of line, underthe center of the tool; then the indented and contracted portion of the tool strikes the flat of the wire and forces it through the openings, g and r, giving it the appearance represented in Fig. 13, while the last operation is being performed the projection, a of the tool, D strikes the wire with the sides of its angular opening, centers it and then cuts it off upon the unbroken edge of the opening, f; the cut off portion of the wire being liberated from the main body, drops through the die into the opening, d of the base; the machine being now fairly started, the cross head continues to descend and the end of the remaining wire is pressedrout as before; now ascending, the wire is pushed forward and stopped; and then descending, first forces the flat portion through the die and then cuts off the round under the projection, a; a wire is thus pressed out, punched, and cut off the proper length, in the joint upward and downward movement of the cross head.

Heretofore, it has required one machine to press out and cut off the wires and another to punch them; one hand being also requisite to attend each machine. With my improvement, however, one machine does the entire work, requires but one hand to attend it, and finishes the work in a more perfect manner. Consequently, facilitating the manufacture, decreasing the cost of production and turning out a more perfect article.

I do not claim, separately, the pressing out, punching, and cutting off in proper lengths, the friction wires for frictional priming, as that has been done before; but

I do claim- 1. The tools, D and E, when arranged in respect to each other and the die, F, substantially as described and for the purpose of pressing out, punching, and cutting off in proper lengths, at one operation, the friction wires for frictional priming.

2. The projection, a with its angular opening, when arranged in respect to the tool, D, substantially as described and for the pur pose specified.

8. The guide, H with its opening, c, when arranged in respect to the tools, D and E, substantially as described and for the purpose specified.

4L. The stop, I and its recess, t, when arranged in respect to the tool, E, substanialy as described and for the purpose speci-- 5. The projection, y with its angular opening, when arranged, in respect to the tool, E, substantially as described and for the purpose specified.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
